I have an old President HR2510 that was made in Taiwan before they were reportedly moved to China to mfg.? Don't know if this makes any difference on my question? This thing has about 80 hrs. of use on it and then stored indoors very carefully for many years. I now turn it on and the display lights up but there is nothing on the display. There is a final (transistor) mounted to the chassis on the left hand side 1/3 way from the front and it gets warm fairly quickly just by turning the radio on with out Xmiting. The inside is super clean and can't see anything evident. Any ideas? Hope I posted in the right section? If not mods please move post. Thank you all in advance,, tracker.
